Plans were developed in 2016 for one surface water intake in Lake Huron and two in the Detroit River that supply Great Lakes Water Authority drinking water treatment plans. While these SWIPPs are not publicly available, this press release was created to let Great Lakes Water Authority customers learn about what is being done to protect their source of drinking water.
The City of Toledo faces a risk of exposure to a hazardous material release due to the concentration of chemical industries and transportation infrastructure located in and around the metropolitan area.

This report summarizes the results of algal bloom tracking efforts by Michigan state agencies in 2017. The survey results will help regulators determine the occurrence and concentration of the cyanobacterial toxin in Michigan surface water supplies.
This 2018 presentation summarizes the GLWA’s work toward converting soluble Phosphorus to particulate Phosphorus during the treatment process using both chemical and biological techniques.
Through this plan, the City of Toledo collaborates with other local, state and federal agencies to respond to and mitigate any hazardous materials incidents that occur in the city. The plan describes the strategy for a coordinated response to a discharge or substantial threat of discharge of oil, a release of a hazardous substance from a vessel, offshore facility, or onshore facility operating within the boundaries of the coastal and inland area of Western Lake Erie.
MAEP is a voluntary verification program that helps farmers reduce environmental impacts from their operations by providing technical assistance for the design and implementation of conservation plans. The Overview describes several other indicators of success that speak to water quality outcomes and farmer engagement including participation in training events and tons of sediment and phosphorus loading reduced.
